Abstract：The double volute with 180° symmetry is widely used in large centrifugal pumps.To study the flow field in the double volute,the flow field in the double volute of HD type petrol-chemical process pump is simulated with the CFD software,by taking the Reynolds Averaged Navier Stokes equations as its governing equations,and the standard k-ε model for turbulence.The results show the distributions of the velocity field and pressure field,especially for the flow in laryngeal and diffuse part.There are refluence on the tongue,but they will not affect the performance and efficiency of the HD pumps.
